''currentApple' is already defined showing in jslint

I have have some js code; in that I ran the js lint. I have this error:

'currentApple' is already defined

Do I need to remove var currentApple from else to make it work?

I'm providing my code below:

if(appleTab == Lifeline){
    var currentApple = appleWorklist.getcurrentAppleTime("currentAppointmentcurrentAppleTime");
    fo.allApples = currentApple;
}
else
{
    var currentApple = appleWorklist.getcurrentAppleTime("CalendarcurrentAppointmentcurrentAppleTime");
    fo.allApples = currentApple;
}

there is no blockscope in javascript, so currentApple in your code snippet is basically the same thingy.

from Douglas Crockford's bible, paragraph Variables:

JavaScript does not have block scope, so defining variables in blocks can confuse programmers who are experienced with other C family languages. Define all variables at the top of the function.

Just declare every used variable once with a var statement at the start of your function.
